METHOD FOR SIMULTANEOUS MEASUREMENT OF RANGE, SPEED AND ACCELERATION OF LOW-SPEED MANEUVERING AIR TARGET IN PULSE-DOPPLER RADAR STATIONS WITH HIGH FREQUENCY OF REPETITION OF PULSES AND LINEAR FREQUENCY MODULATION Russian patent published in 2019 - IPC G01S13/00 G01S13/58 

FIELD: physics.

SUBSTANCE: invention relates to a method for simultaneous measurement of range, speed and acceleration of a low-speed maneuvering air target (AT) in pulse-Doppler radar stations (RLS ID) with high frequency (HF) pulse repetition frequency and linear frequency modulation (LFM) in a RLS ID intended for detection, measurement of primary radar trajectory parameters (PRTP). Detection/measurement of PRTP is carried out based on three packs of probing pulses (PPP) from the chiral coupler. Determination of radial acceleration is carried out by estimating asymmetry of deviations of FPD relative to PPP on the first burst, which is determined during measurement. Velocity is determined from FPD at second and third PPP. Unambiguous determination of range is carried out based on the difference between the FPD measurements on the second and third PPP and using the doubled modulus of symmetrical increments of the chirp of these packs relative to the first PPP and procedures for evaluation/compensation of dynamic errors occurring during measurements.

EFFECT: technical result consists in improvement of information content of measurements and possibility of implementation in standard radar station RLS ID.
